Evaluate the expression for the given value of the variable
1. 8q + 6; q = 2
Plug in 2 for q in the given expression
8(2) + 6= 22
2. 9 + 4g; g = -3
9 + 4(-3) = 9 - 12 = -3
3. 7x - 7 ; x = 4
7(4) - 7 = 28 -7 = 21
4. 10 - 3.2n; n = 2
10 - 3.2(2) = 10 - 6.4 = 3.6
5. 12p + 4; p = 1.5
12(1.5) + 4= 18 + 4 = 22
6. 5w + 10 = 40
Subtract both sides by 10
5w = 30, now divide both sides by 5
w = 6
7. 4y - 12 = 60
Add both sides by 12
4y = 72
Now divide both sides by 4
y = 18
8. 10k + 5 = 65
Subtract both sides by 5
10k = 60, now divide both sides by 10
k = 6
9. 2b - 15 = 33
Add both sides by 15
2b = 48
Now divide both sides by 2
b = 24
10. 3d + 18 = 21
Subtract both sides by 18
3d = 3, now divide both sides by 3
d= 1
Answer:
<h2>5 units</h2>
Step-by-step explanation:
A right angled triangle is a triangle that has one of this angles to be 90°. According to the ΔABC, the angle at B is 90°.
Area of a triangle = 1/2 * base * height
According to the diagram shown, the base is BC and the height is AB which is the required side.
Area of the triangle = 1/2 * BC * AB
Given area of the triangle = 10 square units
BC = 4 units
AB is the required length.
Substituting this values into the formula above;
10 = 1/2 * 4 * AB
10 = 2AB
Dividing both sides by 2
2AB/2 = 10/2
AB = 5 units
Hence the length of AB is 5 units.

think it is c
Step-by-step explanation:
8CM is equivalent to 80 millimeters
<span>3.25 mm = 3.25 cm, 30 cm = 12 inches. So, 12/30 x 3.25 = 1.3</span>
